Image forming device having additional operation mode for additional module

1. An image forming device that forms an image on a print medium, comprising: a printer that executes a process for printing; a memory; a first processor that makes the printer execute a first process when an operation mode of the image forming device is a previously provided standard operation mode; a controller that stores an additional module in the memory by receiving a program module which operates on the image forming device and installing the program module; and a second processor that executes the additional module and thereby makes the printer execute a second process when the operation mode is an additional operation mode, wherein the controller sets the operation mode to the standard operation mode in a case where the additional module has not been installed at a time of startup of the image forming device and sets the operation mode to the additional operation mode in a case where the additional module has been installed at the time of startup of the image forming device, the printer executes a print process for forming an image on a print medium, when the operation mode is set to the standard operation mode, the first processor provides the printer with print data based on reception data received by the image forming device, and when the operation mode is set to the additional operation mode, the second processor executes the additional module and thereby provides the printer with print data based on reception data received by the image forming device.

2. The image forming device according to claim 1 , wherein the printer includes a touch panel that displays information and receives a user operation, when the operation mode is set to the standard operation mode, the touch panel executes the first process, and when the operation mode is set to the additional operation mode, the additional module is executed and thereby the touch panel executes the second process.

3. The image forming device according to claim 2 , wherein the first processor is a panel controller, the second processor is an additional panel controller as a part of the additional module, when the operation mode is set to the standard operation mode, the panel controller controls display and reception of an input on the touch panel, and when the operation mode is set to the additional operation mode, the additional panel controller controls the display and the reception of the input on the touch panel.

4. The image forming device according to claim 3 , wherein in a case where notification of occurrence of failure in the image forming device is made when the operation mode has been set to the additional operation mode, the control of the display and the reception of the input on the touch panel is switched to control by the panel controller and the panel controller controls the touch panel so as to make the notification of the occurrence of the failure.

5. The image forming device according to claim 4 , wherein the control of the display and the reception of the input on the touch panel is returned to control by the additional panel controller in a case where the failure has been recovered when the notification of the occurrence of the failure in the image forming device is made.

6. The image forming device according to claim 1 , wherein the controller sets the operation mode at a time of next startup to the standard operation mode when command information requesting startup in the standard operation mode at the time of the next startup is stored.
